Weblibrary(glmnet) oldfit <-glmnet(x, y, family = "gaussian") newfit <-glmnet(x, y, family = gaussian()) glmnet distinguishes these two cases because the first is a character string, while the second is a GLM family object. Of course if we really wanted to fit this model, we would use the hard-wired version, because it is faster.
